• About L-eNhance Filter

  The relentless spread of urbanization and its associated light pollution have become a growing problem for all amateurs and astrophotographers. The current fixes to the problem can be expensive and might include the purchase of a monochrome camera, several types of narrowband filters and a filter wheel.
  
  L-eNhance provides an economical and practical fix for amateurs. It is a dual-band pass filter which has been designed for DSLR (digital SLR), color CMOS and CCD cameras. 
  
  Optolong believes the design of their L-eNhance filter is a technical innovation among filters. It effectively isolates the H-alpha, H-beta, and Oxygen iii nebula emission lines and achieves a maximum transmission of up to 90-percent. The performance of this filter delivers images that control the impact from light polluted skies.
